The inspiration for this idea came from kaptaink_cg. Props for getting us going! His instructable can be found here: https://www.instructables.com/id/Camera-mount-for-a-motorcycle/
I decided to build upon the original idea of putting a camera on the rear footpeg of my motorcycle but wanted to add some flexibility on the camera angles by using L-shaped brackets and tightening them with bolts, nuts and lock washers to hold them in position while riding.
As a result, I came up with this new design that works for my Honda Nighthawk 250 and I'm sure all footpegs might be the same but double checking your motorcycle pegs wouldn't hurt before starting this instructable.
Step 1: Gather the Materials
2x small bolts
1x medium bolt
1x 1" corner bracket
1x 2-1/2" corner bracket
2x wing nuts
2x metal flat washers
3x hex nuts
4x lock washers
Step 2: Assembly
Assemble the materials as depicted. Use the pliers and screwdriver to assist you in tightening the hex nuts.
Step 3: Bolt to Footpeg
Bolt to Footpeg as depicted. Again, use the pliers and screwdriver to assist you in tightening the hex nuts.
Step 4: Complete!
That's pretty much it! Mount your camera and start filming.
I decided to duplicate this instructable and build a rig for the other footpeg as well and flipped the camera 180 degrees for rear cam footage.
Don't forget that this rig can be folded in and out of the way when not in use.
